The basic system of a lock, so that a key is used to move a metal pin in a hole in the door frame is essentially the same across designs. However, the manner in which this is achieved has changed and evolved over time.

In the old days, when most of the locks used the key of the door itself, this was a rather simple (although the earliest form of the lock was actually found in ancient Egypt). Door keys, still used today, though mainly as a deterrent / design feature large door and churches, have a simple anatomy that consists of one page (actually the 'key' bit that works with the mechanism) near the end and a long handle that holds the blade at a right angle. This means that only a very limited number of permeations are possible, since only the distance from leaf the end of the key and its size is what determines who will be integrated lock and a persistent thief could easily double or rotate the key lock mechanism by other means.
